Matthew Henry Commentary23:12-16 Here is a parent instructing his child to give his mind to the Scriptures. Here is a parent correcting his child: accompanied with prayer, and blessed of God, it may prove a means of preventing his destruction. Here is a parent encouraging his child, telling him what would be for his good. And what a comfort it would be, if herein he answered his expectation! 17,18. The believer's expectation shall not be disappointed; the end of his trials, and of the sinner's prosperity, is at hand.
